Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a single lamp is recessed in a corner of the upper wall to illuminate the tank, then the lamp is protected from water or steam circulating in the tank, but the illumination is uneven and the operator is dazzled
Solution Approach 1:
The invention divides the single corner lamp into multiple lighting units distributed along the transparent wall. Each unit contains multiple LEDs arranged in rows, creating segmented illumination zones that collectively provide even coverage across the entire tank without concentrating light in one location.
Solution Approach 2:
The invention introduces a diffusing element as an intermediary between the LEDs and the tank interior. This diffuser scatters the light from each LED to create a more uniform illumination pattern, preventing direct glare while maintaining even lighting across the washing chamber.
2Device complexity
If a single lamp is recessed in a corner of the upper wall, then the structure is simple, but the operator cannot view the operating status from a distance when multiple devices are placed side by side
Solution Approach 1:
The lighting system is segmented into multiple independent units distributed along the transparent wall, with each unit providing localized illumination and visibility. This segmentation allows operators to view specific areas of interest while maintaining overall system simplicity through modular design.
Solution Approach 2:
The invention transitions from a single-point light source in the upper wall to a distributed linear arrangement along the transparent wall. This dimensional change from point to line distribution provides continuous visibility along the tank length, enabling operators to monitor operating status from various distances and angles.
3Illumination intensity
If lighting means are mounted inside the tank to illuminate evenly, then illumination homogeneity is improved, but the lighting means are exposed to water and steam
Solution Approach 1:
The invention uses the transparent wall as an intermediary barrier between the lighting means and the water/steam environment. The LEDs and diffusing elements are mounted on the external surface of the transparent wall, which transmits light while providing reliable protection from moisture and steam exposure.
Solution Approach 2:
The lighting effect is copied to the external surface of the transparent wall through the use of LEDs and diffusers. This creates the appearance of internal illumination while actually placing all lighting components in the protected external environment, eliminating exposure to water and steam.
4Loss of information
If the transparent wall is made larger to improve visibility, then operator visibility is improved, but the structural strength and sealing are compromised
Solution Approach 1:
The transparent wall is segmented into a fixed structural portion and a movable door portion with integrated lighting. This segmentation allows the fixed portion to maintain optimal structural strength while the movable portion provides enhanced visibility and lighting functionality, balancing strength and visibility requirements.
Solution Approach 2:
The transparent wall has different functional zones: the fixed portion prioritizes structural strength and sealing, while the movable door portion integrates lighting and control features for enhanced visibility. This local differentiation of quality allows the system to optimize both strength and visibility in appropriate locations.
